dynamic-routes

A dynamic router / loader for http://expressjs.com/

Install

npm install dynamic-routes --save

Usage

DynamicRoutes(app, path_to_routes, [options])

Examples :

Express.JS Server :

var express = require('express'),
	http = require('http'),
	path = require('path'),
	DynamicRoutes = require('dynamic-routes'),
	app = express();

app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.use(express.logger('dev'));
app.use(bodyParser());
app.use(express.methodOverride());
app.use(express.cookieParser('secrets secrets, we got extra'));
app.use(express.session());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));

if ('development' == app.get('env')) {
	app.use(express.errorHandler());
}

DynamicRoutes(app, __dirname + '/routes/');
// or

/*
DynamicRoutes(app, {
	src: __dirname + '/routes/',
	ignore: [],
	pattern: /\.js$/
});
*/

http.createServer(app).listen(app.get('port'), function(){
	console.log('Express server listening on port ' + app.get('port'));
});

Creating compatible routes :

Using an object :

//routes/index.js
module.exports = {
	priority: 1000, //this is the `/` handler, therefore it should be the last route.
	path: '/',

	//this function gets passed the express object one time for any extra setup
	init: function(app) {
		
	},
    
    //a middleware that is called from any HTTP methods
    ALL: function(req, res, next) {
        res.send(' - Common Middleware -');
        next();
    }
    
    //HTTP method specific routes
	GET: function(req, res) {
		res.end('GET ');
	},
	
	POST: function(req, res) {
        res.json(req.body);
        res.end('POST ');
	},
    
    //routes supports GET, HEAD, POST, PUT, DELETE, OPTIONS, TRACE, PATCH method(all uppercase)
};

Routing multiple middlewares by assigning an array of middlewares :

module.exports = {
    priority: 1000,
    path: '/',
    
    init: function(app){
        
    }
    
    ALL: [
        function(req, res, next){
            res.send(' - Common Middleware 1 - ');
            next();
        },
        function(req, res, next){
            res.send(' - Common Middleware 2 - ');
            next();
        }
    ],
    
    GET: [
        function(req, res, next){
            res.send(' GET 1 ');
            next();
        },
        function(req, res){
            res.end('end of GET');
        }
    ],
    
    POST: [
        function(req, res){
            res.json(req.body);
            res.end('end of POST');
        }
    ]
    /* an array with single route, that is equivalent to
    
    POST: function(req, res){
        res.json(req.body);
        res.end('end of POST');
    }
    
    */
}

Using a function :

var user = module.exports = function(app) {
	"use strict";
	//other setup
	app.get(function(req, res) {
		res.json({'user': [req.params.id, req.params, req.query, req.body]});
	});
};

user.priority = 1;
user.path = '/user/:id?';

This is equivalent to :

module.exports = {
	path: '/user/:id?',
	priority: 1,
	init: function (app) {
		//setup db
	},
	
	GET: function(req, res) {
		res.json({'user': [req.params.id, req.params, req.query, req.body]});
	}
}

Notes

• As of Express 4.x, it's recommended to use require('body-parser')() instead of express.bodyParser(), check this.
